You can find the latest version, I am still working on, in the wordpress svn. The URL to the branch is: http://svn.wp-plugins.org/apml/branches/refactoring/
I removed the whole „search/compare“ feature and added the ability to extend the APML-Feed through other Plugins.
I will tweak only some small things before I will release it as final version.
Any feedback is very welcome 🙂
